Abstract: ABSTRACT           There is disclosed a strapping machine for applying a plastic strap around an object, tensioning the strap and heat-sealing together overlapping portions of the strap, including a retractable heating member movable between the overlapping strap portions and a pressure-applying means including a pressure block with a tiltable universal joint coupling for pressing the overlapping strap portions against the heating element with a first relatively light pressure to melt the facing surfaces thereof.  The heating element is withdrawn while the pressure-applying means presses the strap thereagainst with the first pressure, and then the melted strap portions are pressed together with a strong second pressure to complete the seal.  A cam with a yieldable section controls the first pressure and a compression spring controls the second pressure.  While retracted, the heating element is raised to a higher temperature for burn-off of strap residues.  Switch means disposed in the strap path provide a positive stop to prevent strap overfeed while a yieldable track section permits escape of excess strap from the path to prevent jamming. Air filter means remove waste products of the heat-sealing operation.

Abstract: Abstract An insulator suitable for use with a truncated triangular shaped support member or skid pipe having a base member, a pair of converging side members which terminate in an apex member and a pair of shoulders extending oppositely one another from the joinder of the apex member and each corresponding side member.  The insulator includes a base unit and a pair of converging side walls.  When slidingly received around the skid pipe, the insulator closely con-forms to the periphery of the base member and side members of the skid pipe.  The side walls of the insulator pre-rerably abut a lower lip of each shoulder so that molten slag and other impurities cannot migrate between the insulator and the skid pipe to degrade and dislodge the insulator.  The insulator is secured to the support member by its novel geometry; that is, when the insulator is slidingly received around the structural member, the converging side walls of the insulator bear against the converging side members of the structural member thereby maintaining the insulator in proper position on the structural member.

Abstract: ABSTRACT     In order to improve the operable frequency of a program-mable counter circuit which serves as an N-step counter by loading an initial value N, load terminals of flip-flops of respective stages forming the counter circuit are sequentially cascade-connected via buffers and a load signal is applied to each of the load terminals from a load signal generator circuit.          By a detector circuit is detected a specified value which is provided a little before the initial value loading of the counter circuit.  The detected output is shifted by a shift register which operates on the same clock signal as that for driving the counter circuit, thereby to generate the load signal at the moment of the initial value loading of the counter circuit.  In this case, for the duration of the load signal and a certain period of time subsequent thereto the application of the output from the detector circuit to the shift register is inhibited, thus preventing erroneous loading.

Abstract: 48,779 ABSTRACT OF THE DISCLOSURE         A method and system for allocating fluid flow draining from a fluid utilizing apparatus to first and second fluid sinks.  The fluid flow is entirely routed to the first fluid sink for drain flow rates less than a predetermined flow rate and to the second fluid sink as well as the first fluid sink for drain flow rates at least as great as the predetermined flow rate.  Fluid from the fluid utilizing device is received in a drain tank through an inlet port and is drained therefrom through an outlet port.   The  fluid  flow rate through the outlet port  is regulated by  cooperatively modulating  first  and  second valves  arranged  in parallel  flow  relation  to  allocate fluid  flow  to  the  first  and  second  fluid  sinks. The valves are modulated to provide a fluid flow rate through the drain tank's outlet port of substantially equal magni-tude to the fluid flow rate entering the inlet port.  The inlet and outlet fluid flow rates are equalized by modu-lating the valves in response to signals which are indica-tive of the drain tank's fluid level.   First and second parallel acting signal generators detect the fluid level in the drain tank and generate the fluid level indicator signals.  The first signal generator's signal is normally transmitted to the first valve which modulates in response thereto to maintain the desired drain tank fluid level. The second signal generator normally provides a drain tank level  indication signal to the second valve which modu-lates  for signals indicative of drain tank fluid levels greater  than  a  predetermined  height.   Signal  monitors 16                  48,779 provide means for detecting erroneous signals generated by the first and second signal generators.  If an erroneous signal, as indicated by a signal being out of a predeter-mined  range,  from  one  signal  generator  is  monitored, transmission of that signal  to its respective valve is obstructed  and  the  other  signal  generator's  signal  is transmitted to both valves.   Since two identical signal generators are used to supply the signals to the valves, either signal generator can provide the signal while the other signal generator is isolated and replaced or re-paired during operation of the fluid utilizing apparatus.
